TEMPE, Ariz. -- Former Cardinals quarterback Ryan Lindley has a new job and it just happens to be with Arizona's Week 1 opponent.
Coincidence? Maybe. Maybe not.
Either way, the Cardinals will have to protect themselves from Lindley's intimate and deep well of knowledge of their playbook, which he had to turn in after being cut on Aug. 26. He was signed to the Chargers' practice squad Sunday after spending about 20 months in Arians' system.
"It's definitely going to put a little wrinkle in our operation, I would say, because as a quarterback he knows everything that's going on," wide receiver Larry Fitzgerald said. "It's one thing to know it and another thing to stop it and know when it's coming.
"I don't think we're going to deviate from the plan much."
Quarterback Carson Palmer sided with Fitzgerald. Not a lot will change, mostly because the Cardinals' playbook is so deep, Palmer said. But once Arizona starts prepping for San Diego, it'll change the code words and a few other small nuances that Lindley would know.
"It's totally different when a quarterback goes," Arians said. "That hasn't happened very often."
While Arizona's signing of former San Diego linebacker Thomas Keiser appears to be an act of gamesmanship, Arians assured that it wasn't. The Cardinals need help with their pass rush more than they need a few secrets about the Chargers.
Even so, Keiser said Tuesday that the Cardinals' coaches haven't debriefed him on his former team. If and when they do, it may not help that much, Arians said.
"I think Ryan probably knows a whole lot more about both sides of the ball than Tom does," Arians said. "He knows how to rush the passer. I don't know what he's going to tell me about Philip's (Rivers) offense, but Ryan does know a lot about both sides of the ball."
Monday will be a rare meeting for both teams, since they played in the preseason finale on Thursday. But Arians said he couldn't glean anything from that game, which turned into an ugly tryout between third stringers on both sides.
Lindley, who was released by then, never took a snap under Arians, watching behind backup Drew Stanton as Palmer played in all 16 games in 2013. But with two training camps in Arizona's offense, Lindley has seen the good, the bad and the ugly of it. He also knows the intricacies of a very complex scheme.
Having a former teammate -- and a recent one at that -- take a wealth of information to another team is always dangerous and it'll help the Chargers in some regard, Palmer believes, but Arizona can't veer from its course because of Lindley.
"We do a lot so it's tough to get a beat on exactly what we're trying to do in a certain formation or a certain personnel group," Palmer said. "We're on the offense and Bruce is of the mindset that you play offense, you don't play defensively offensively. We are going to attack and we are going to do what we do and they have to counter.
"They might have a beat on a thing here or there but we have to stick with our rules and stick with what we have been doing and what we have been working on and we will be fine."
